has anyone heard of the Tavistock institute of human relations

they're a british think tank, there is a lot of conspiratorial ideas surrounding them, many sinister, they are based in the capital London, some i spoke to in years goneby think they are involved in mind control for malicious purposes...someone i spoke with a long time ago even thought certain workers for the institute could make people's heads explode, literally.

i'm aware the Tavistock institute have a website, but i've never visited.
